Abstract

Oxygen usage has played a crucial role in the ongoing EAF process improvement and has enabled furnace operators to optimize the chemical energy input, reaching unprecedented efficiencies and productivity. This article will present the fundamental principles governing the design of an optimized chemical energy system through scrap oxy-cutting and melting, decarburisation, post-combustion and slag foaming. It will be illustrated with industrial results obtained at the Vallourec Mannesmann Saint-Saulve site, where a PyreJetTM and ALARCTM PC system, using the newly designed DRAGON Panel, has been recently commissioned.
